LATCH I OR VEHICLE DOORS.

Specification of Letters Patent, Patented lIfll. 28, 1922- Applicationfiled August 2, 1921.- Serial No. 489,264.

To all whom it may concern.

Be it known that. I, RICHARD V; KAIMER,

' a citizen of the United States, residing at New Haven, in thecounty ofNew Haven and State of Connecticut, have invented a new and usefulImprovement in Latches i'or Vehicle Doors; and Ido hereby declare thefollowing, when taken in connection with the accoi'npanying drawings andthe characters of reference marked thereon, tobe a full, clear, andexact description of the same, and which said drawings constitute partof this application, and represent, in- I Fig. l a side view of a handlefor vehicle door latches constructed in accordance with my invention andshown as applied to the upper end of the latch-spindle. i Fig. 2 avertical sectional view of .the

same. I

This invention relates to improvement in latches for vehicle doors andis an improve ment particularly to latches which are operated in part bya pushebutton mounted in a vertically-arranged rotatable latch-spindle,and is an improvement in the device shown and described in anapplication filed May 17. 1921, Serial No. 470,366.

In the device shown in the said application, the handle was secured tothe spindle y means of a frictional clamp. A more convenient means ofsecuring the handle to the spindle is to flatten two sides of thespindle and provide the hub of the handle with two flat faces to engagetherewith, and secure the handle to the spindle by a nut, and the objectof this invention is to provide means for attaching a handle to alatchspindleand provide an operating push-button which will extend upthrough the handle, and the invention consists in the con struction ashereinafter described and particularly recited in the claims.

In carrying out my invention I employ the usual latch-spindle 5, whichis a vertical spindle adapted to be rotated for the movement of thelock, as in the application above referred to, and around this spindleis a sleeve 6 adapted to be pressed downward by means of atransverse-pin 7 operated by a push-rod 8. In this construction, theupper end of the. spindle is formed on line 44 of central bore for thebutton.

opposite sides with flattened faces 19 and 10,

and that end is threaded to receive a nut 11 which enters a recess 12 inthe hub 13 of a handle 14, this nut having a central opening 15 for thepassage through it of a button 16 on the end of the push-rod 5.

Preferably, and as shown, this nut is polygonal, so that it may bereadily'applied by suitable wrench and serves not only to I hold thepush-button in place but to secure the handle to the end ofthe spindle.

' 'With this construction, the handle is' firmly secured to the spindle,and the pushbutton mounted in the spindle for coaction with the slidingsleeve thereon, and the handle brought down closer to the door casingthan was possible in the construction shown in the said priorapplication.

I claim:

1. The combination with a vertically-arranged, rotatable latch-spindlehaving its outer end flattened on opposite sides and with a centralbore, a push-rod mounted in said bore. and formed with a push-buttonprojecting above-the upper end of the spindle. a handle formed to fitthe flattened end of the spindle and formed with a chamber into whichthespindle extends, and a nut entering the said chamber and engagingwith the upper end of the spindle, the said nut forme'dwith a centralopening for the passage of the push-button.

2. The combination with a vertically-arranged rotatable latch-spindlehaving its outer end flattened on opposite sides and with 'a centralbore, a push-rod mounted in said bore and formed with a push-buttonprojecting above the upper end of the spindle, a handle formed to fitthe flattened end of the spindle and'iormed with a chamber intowhich thespindle extends, and a nut entering the said chamber and engaging withthe upper end of the spindle,the said nut formed with a polygonal headand a passage of the said push- In testimony whereof, I have signed thisspecification in the presence of two subscribing witnesses.
